Abstract

1. A process for the biological purification of phosphate-containing waste water, in which, in the presence of activated sludge, the incoming waste water is aerobically treated for the decomposition of organic hydrocarbon compounds and the absorption of phosphate, by micro-organisms present in the activated sludge, and the waste water/activated sludge mixture is subsequently divided into purified, essentially phosphate-free water and phosphate-containing sludge which is at least partially recycled as return sludge, characterised in that, prior to the aerobic treatment, at least a part stream of the waste water is mixed with at least a part stream of the return sludge in an anaerobic mixing zone and thereafter is subjected partially to the aerobic treatment and partially to a phosphate separation ; and in that the phosphate-poor sludge, which accumulates during the phosphate-separation step, is at least partially fed to the aerobic treatment and the resulting liquid, which is enriched with phosphate, is further treated.
